Progesterone API Powder Supplier

Progesterone binds specifically to intracellular progesterone receptors (PR), then translocates into the nucleus to modulate gene expression in reproductive tissues.

Promotes endometrial glandular secretory transformation, preparing uterine lining for embryo implantation;

Reduces uterine smooth muscle excitability and contraction risk;

Supports corpus luteum function during early gestation;

Balances estrogen effects in hormone replacement therapy to prevent endometrial hyperplasia;

Inhibits gonadotropin release from the pituitary gland to suppress ovulation for contraceptive formulations.

Notably, progesterone belongs to BCS Class II: high permeability but very low aqueous solubility. Micronization reduces particle size and increases surface area, greatly improving dissolution rate and oral bioavailability, which is the most common upgrade for oral and vaginal dosage forms.

Frequently Asked Questions (FAQ)

Q1: What is micronized progesterone API?

A: Micronized progesterone is chemically identical to standard progesterone, processed by micronization to reduce particle size. Fine particles improve dissolution and oral/vaginal absorption, widely used for Utrogestan-type vaginal and oral capsule formulations.

Q2: What pharmacopoeia versions can you supply?

A: We provide progesterone API complying with USP, EP and BP monographs. Custom internal specifications are available for special regional registration.

Q3: Can I get free samples for lab formulation test?

A: Yes, small trial samples are available for quality and dissolution testing before bulk order. Sample freight cost to be confirmed.

Q4: What documents will be provided together with shipment?

A: Commercial invoice, packing list, COA, HPLC chromatogram, SDS, GMP copy. We can prepare extra supporting files upon your registration requirement.

Q5: What is your MOQ and lead time?

A: Our MOQ is [fill your MOQ]. Stock goods can ship in 3–7 working days; bulk production order takes around 15–25 working days.
